A metallic circular plate with radius r is fixed to a tabletop. An identical circular plate supported from above by a cable is fixed in place a distance dd above the first plate. Assume that dd is much smaller than r. The two plates are attached by wires to a battery that supplies voltage V. 1) What is the tension in the cable? Neglect the weight of the plate. Express your answer in terms of the variables d, r, V,...

A circular coil with a radius of 0.4 meters wrapped 47 times is spun at a frequency of 21 Hz in a uniform magnetic field to form a generator. It is then connected to the primary transformer. The primary side has 36 turns and the secondary side has 15 turns. The maximum secondary current is 6 amps and the resistance of the coil on the primary side is 3 Ohms. What is the amount of the magnetic field in the...

Charlie and Alexandra are running around a circular track with radius 60 meters. Charlie started at the westernmost point of the track, and, at the same time, Alexandra started at the northernmost point. They both run counterclockwise. Alexandra runs at 4 meters per second, and will take exactly 3 minutes to catch up to Charlie. Impose a coordinate system with units in meters where the origin is at the center of the circular track, and give the x- and y-coordinates...
